Changes since version 3.1.5:

New features and improvements:

  - Added a new statistics counter named "called for preprocessing".

  - The original command line is now logged to the file specified with
    CCACHE_LOGFILE.

  - Improved error logging when system calls fail.

  - Added support for rewriting absolute paths in -F/-iframework GCC
    options.

  - Improved order of statistics counters in "ccache -s" output.

Bug fixes:

  - The -MF/-MT/-MQ options with concatenated argument are now handled
    correctly when they are last on the command line.

  - ccache is now bug compatible with GCC for the -MT/-MQ options with
    concatenated arguments.

  - Fixed a minor memory leak.

  - Systems that lack (and don't need to be linked with) libm are now
    supported.
